RAZOR STROP AND THE PREPARATION THEREOF.

No Drawing.

Our invention has reference to razor strops, and the method of preparing the same for use, the purpose thereof being to produce a strop which will possess a maximum of efficiency, which will be durable, and which will not be affected by atmospheric conditions, such as will ordinarily cause the strop to buckle, and get out of shape for use.

The invention is more specially designed for use in a strop formed of canvas or other fibrous material, and the preparation thereof consists in applying thereto an emulsion of a novel character, and adapted to act as a filler. The strop is thereby prepared to receive another and different emulsion, also of a novel character, and which forms a coat or dressing therefor. The two emulsions, or compounds, are dependent to a large extent upon each other, but another preparation might be substituted for the filler emulsion, and the dressing compound act as efiiciently therewith.

The first mentioned, or filler emulsion, is made up of the following ingredients, in approximately the proportions mentioned, to wit: water, 16 ounces; wood oil, 8 ounces; cotton-seed oil, 8 ounces; commercial soap, 7 drams and 20 grains. The strop tobe prepared is saturated with the compound formed by thoroughly mixing said ingredients, the emulsion penetrating all of the fibers contained in the strop, and acting as a perfect filler therefor, fully excluding any other compound, and preparing the strop to receive the dressingcoat, which is made up of the following ingredients, also thoroughly mixed with each other, to wit:

ater, 16 ounces; wood-oil, 8 ounces;

Application filed October 4, 1924. Serial No, 741,760.

olive oil 2 ounces; calcium carbonate, .1 and 4 ounces; zinc oxide, 1 and ounces; white bees-wax, 8 drams and 20 grains; commercial soap, 7 drams an 20 grains. This second emulsion is applied to the strop in the usual manner for forming a dressing thereon, to be used in putting an edge on the blade of a razor. The strop forms the base, and, when provided with the filler compound, serves as the ground for the final application, or dressing coat. In the stropping operation the strop also serves as a supporting member, to receive the strokes of the razor, and is also a carrier for the compounds which have been applied thereto.

It will be evident that changes can be made in the proportions of the various ingredients in either of the compounds, within reasonable limits, without departing from the scope or usefulness thereof. A.strop formed in the above described manner will always be soft and pliable, and specially fitted for the use for which it is intended.

What we claim, and desire to secure by Letters Patent, isz- In a razor strop preparation, a dressing emulsion, consisting of the following in gredients thoroughly mixed together, and in approximately the proportions named. to wit: water, 16 ounces; wood oil, 8 ounces; olive oil, 2 ounces; calcium carbonate, 1 and ounces; zinc oxide, 1 and ounces ;white bees-wax, 3 drams and 20 grains; and conimercial soap, 7 drams and 20 grains.

In testimony whereof we aifiX our signatures.
